Weather Forecast Voice System

Weather Forecast Voice System

This paper introduces Weather Voice System applied to information commands-responses system through Public Switched Telephone Network (PSTN). Being able to understand users' voice commands, our system would assist them during their searching weather forecast in Vietnamese towns and cities by communicating in Vietnamese through Telephone Network. What makes this system different from others consists of its ability to analyze syntax and semantics of voice commands after their being recognized by speech recognizer component. Weather Voice is composed of main components that are there: 1) Telephone network communicator, 2) Vietnamese speech recognizer, 3) Natural language processor, and 4) Vietnamese speech synthesizer. To the best of our knowledge, this is one of the first systems in Vietnam to combine text language processing and speech processing. This event could make voice applications more intelligent with aim to communicate with humans in natural language at high precision and at quick speed. The fact that experiments have proved our expectation as well as the friendliness of the system to users reveals the practicality of our research.
